The answers are B and D hope this helps.
The interior angles of a quadrilateral( 4 sided figure) add up to 360 degrees.
114 + 84 + 94 + x = 360
292 + x = 360
x = 360 - 292
x = 68 <== ur missing angle
Answer:
0.9325
Step-by-step explanation:
Given
n = sample size = 80
p = probability = 0.4
q = 1 – p = 0..6
standard deviation for the proportion = √ (p * q) /n = √(0.4*0.6)/80 = 0.0547
for the proportion mean is 0.4
now we can find z and the probability
P (0.3<mean<0.5) = P((0.3– 0.4)/0.0547 < z < (0.5– 0.4)/0.0547)
P (0.3<mean<0.5) = P(-1.828< z < 1.828)
Using a z table
P (0.3<mean<0.5) = 0.9325
Perpendicular
Bit confusing but that should be right
Hi!
First of all, we can look and see that these sqaure roots are the same, so it's easy to add.
In square roots, if the number INSIDE the square root is the same, it stays that way for the answer .
So the equation is 9(square root) 5 + 4(square root) 5.
The numbers out the sqaure root can just be added. So 9+4 = 13.
Lastly just attach the sqaure root onto the 13
Final answer should be 13(square root)5
***use the actual symbol in place of (sqaure root)
I hope this helps!
